The UTC oversees energy conservation services offered by regulated utilities. Conservation is defined as any reduction in energy consumption resulting from increases in the efficiency of energy use, production, or distribution. 

UTC staff review the development of conservation potential assessments, which use a variety of data sources to estimate how much conservation is available in the current building stock. UTC staff attend advisory group meetings and review conservation program designs, the setting of savings targets and development of budgets. Electric aMW savings targets are set through the Biennial Conservation Plan filings, and natural gas therm savings targets are set through the IRP process. UTC staff then review annual and semi-annual reports on conservation spending and conservation savings, and cost-effectiveness of conservation acquisition.
